( this bug might be related to bug #17246 ) here a small example: function pass_by_reference( &$param ) { $param[] = "another entry"; } $data = array( "a first entry" ); call_user_func( "pass_by_reference", $data ); var_dump($data); // $data contains only one element ( "a first entry" ) ( == unexpected behaviour ) $data = array( "a first entry" ); call_user_func( "pass_by_reference", &$data ); // Warning: Call-time pass-by-reference has been deprecated - argument passed by value; ... var_dump($data); // $data contains both elements ( "a first entry", "another entry" ) ( == expected behaviour ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=17309&edit=1
